Synopsis by Rob Ferrier
Each episode of Sharks of Steel takes viewers inside the world of the submarine and the submariners who serve aboard them. Used as weapons for over a hundred years, it was during the world wars that submarines first scratched the surface of their potential, acting mainly as commerce raiders. Later, when nuclear weaponry came of age, submarines became an integral part of this force. This episode examines the procedures used by crews when something goes horribly wrong aboard one of their craft. From attempts to save the ship itself to techniques used to save the people inside, this is an in-depth look at a dangerous job.
